I want to accept payment from customers who don't have paypal account.

I want to take online payments from customers who don't have paypal account. Is it possible through this?

Yes, this is now possible where the "Paypal account is optional" should be enabled on your account.

Using the Paypal Checkout payment gateway is also another way of letting your users pay using a credit card. However, this integration requires a business account: How-to-Integrate-Form-to-PayPal-Checkout
